I want to replace the onboard AMS1117-5.0 (broken) with a LM7805.
However, the pinout is different between the two voltage regulators; AMS1117: Gnd, Vout, Vin vs LM7805: Vin, Gnd, Vout.
I would like to know what is the best practice of how to approach this? Line-up the Vin and cross the Vout and Ground pins and add some insulation so they dont make contact. How do the experts at EESX do this?
Follow-up: adding the lm7805 using jumper wires works fine with the 12v DC input i have. It is a temporary fix until replacement ams1117 arrive.

Why do you need to change over to a 7805? If you're gonna be bending pins up and using jumper wires, you're cruisin' for a bruisin'. A quick look at the data sheets leads me to believe there is no good reason to switch, other than the possibility that this is all you've got on hand?
If it must be done, here's how I'd do it: bend the large ground tab so that the LDO will sit at a large incline off the plane of the board. Tack it on, then solder your jumper wires from the pads to the appropriate connections.
I do not recommend doing this, just sample a replacement part. You'll get it for free, and have the satisfaction of a job well done.
